Why you don't test with FMU

I learned yesterday not to test with my first morning urine (FMU) with an OPK because the LH rise usually begins in the early morning while you are sleeping and it takes 4-6 hours for it to appear in your urine after that. For this reason, first morning urine may not give the best result. Testing mid-day is usually recommended. It is important to follow the instructions of your OPK for maximum results.
Here's my OPK Cycle day 10 with FMU
